Populations of the lesser white-toothed shrew, Crocidura suaveolens (Pallas, 1811), from Corsica show an increase in adult body size associated with a decrease in litter size. The average number of embryos in wild Corsican females is smaller (mean 2.6, n = 62) than in mainland females (mean 4.6, n = 173). A breeding experiment was run for 4 years, yielding three generations. Under standard breeding conditions, the differences between island and mainland populations were maintained and were significant (median litter size was 2 for Corsica and 5 for the mainland). These differences in life-history traits were therefore proved experimentally to be genetically determined. Hypotheses concerning the mechanisms responsible for these differences are discussed.

Adult Body

A poor start in life owing to a restricted diet can have readily detectable detrimental consequences for many adult life-history traits. However, some costs such as smaller adult body size are potentially eliminated when individuals modify their development. For example, male mosquitofish ( Gambusia holbrooki ) that have reduced early food intake undergo compensatory growth and delay maturation so that they eventually mature at the same size as males that develop normally. But do subtle effects of a poor start persist? Specifically, does a male's developmental history affect his subsequent attractiveness to females? Females prefer to associate with larger males but, controlling for body length, we show that females spent less time in association with males that underwent compensatory growth than with males that developed normally.

The Western Ghats have a high level of anuran endemism.  Although there has been an extensive focus on their taxonomy, the ecology of most species are poorly known.  In this note we describe the reproductive life-history traits and breeding behavior of four species of endemic bush frogs, Pseudophilautus wynaadensis, Raorchestes akroparallagi, Raorchestes glandulosus, and Raorchestes ponmudi (Amphibia: Anura: Rachophoridae) from Wayanad region of Western Ghats.

Reproductive Life History

Pumpkinseed (Lepomis gibbosus) inhabiting two shallow ponds that experienced major winterkills matured 1–2 yr earlier and at a smaller size (difference > 20 mm in length) than conspecifics living in an adjacent, nonwinterkill lake. Pond females were more fecund relative to body weight, and their gonadosomatic index was about double that of lake females. Pond males showed a significant, but less drastic increase in gonadosomatic index over lake males. Winterkills occurred in different years in the two ponds, but in both cases, pumpkinseeds showed significantly lower age and size at maturity following winterkill in comparison with a preceding or subsequent nonwinterkill year. These results are consistent with life history predictions for organisms living in fluctuating environments and indicate that reproductive life history traits are very plastic in pumpkinseeds living in high-risk environments. Advanced maturity following winterkill may be the result of abundant food supply to survivors or release from social factors that prevent maturation of small pumpkinseeds.
